Simple Instruction Set Control

The DTP T HWP D and DTP T UWP D family of extenders can be remotely controlled using SIS commands from a host device such as a computer or control system via its rear panel

Remote RS-232 port (see item C on pages 9 and 11) or front panel Configuration (USB) port (see item C on page 8, and D on page 10).

The default serial port protocol of the port is as follows:

9600 baud

No flow control

No parity

8 data bits

1 stop bit

Host-to-Extender Communications

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command character sequence. When a command is valid, the extender executes the command and sends a response to the host device. All responses from the extender to the host end with a carriage return and a line feed (CR/LF = ]), which signals the end of the response character string. A string is one or more characters.

Extender-Initiated Messages

When a local event occurs, such as a front panel operation, loss or restoration of an input signal, or an error condition, the extender responds by sending a message to the host. Examples of the extender-initiated messages are listed below:

© Copyright 20yy, Extron Electronics DTP T HWP 232 D, Vx.xx, 60-nnnn-nn]

The extender issues the copyright message when it first powers on. Vx.xx is the firmware version number and 60-nnnn-nnis the part number.

Inn All]

The extender also sends the Inn message whenever the selected input is changed. n is the input number. A 0 in the n field indicates no input is selected.

Error Responses

When the extender receives a valid SIS command, it executes the command and sends a response to the host device. If the extender is unable to execute the command because the command is invalid or it contains invalid parameters, the extender returns an error response to the host. The error response codes are:

E01 — Invalid input channel number (out of range)

E06 — Invalid channel change

E10 — Invalid command

E13 — Invalid parameter

Timeout

Pauses of 10 seconds or longer between command ASCII characters result in a timeout. The command operation is aborted with no other indication.
